General Security Sharing School license Assessment Data & export Technical

General

What is ClassCheck?
ClassCheck is a digital assessment tool for teachers. It replaces the handwritten grade book: you create classes, add assessment columns, and enter grades with a keyboard or a touchscreen. ClassCheck calculates weighted averages automatically and produces PDFs for conferences or parents.
Who is ClassCheck for?
For teachers in schools, vocational schools, and higher education. Students do not sign in — ClassCheck is a tool for you, not a learning platform.
Is ClassCheck free?
You get every feature for 2 months. There is no automatic charge. After that the account stays: you can still view and export PDF, Excel, and JSON. Edits return when you take the license for €15/year or use a school license (€99/year, up to 40 teachers). You can close the account yourself. Data is not deleted automatically after the trial.
Which grading systems are supported?
+/~/-, */+/./-, grades 1–5, grades 1–6, A–F, percentage, points (with a maximum score), yes/no, counter, attendance, absences, achievements, and custom scales. Several systems can be used in one table. Details: Grading systems.
How do I count a vocabulary champion that counts toward the grade?
Create an achievement column (in the “Custom column” dialog). Plus raises the counter by 1. Each success counts, at the value you set, toward a category such as classwork. A plus on the plus/wave/minus scale is 100%. An existing counter is not converted. How the achievement column works.
Which languages is ClassCheck available in?
ClassCheck is available in German and English. The switch is in the top bar.
Does ClassCheck work on a phone or tablet?
Yes. ClassCheck is a progressive web app (PWA) — usable in the browser and, if you want, installable as an app (Chrome / Safari: “Add to Home Screen”). On a touchscreen, a long press opens context menus.

Security & privacy

Is my data safe?
Until you open a subject, student names are stored with AES-256 and ClassCheck can still read them. On the first open, your login password encrypts the names in the browser. After that, ClassCheck cannot read those names. Passwords use bcrypt. Details: encryption.
Where are the servers? Is this GDPR compliant?
All servers are in the EU (Germany, a Hetzner data center). ClassCheck is GDPR compliant: a data processing agreement (DPA) is available, along with data minimization and the rights of access, erasure, and rectification. Details: Privacy policy.
Can I turn on two-factor authentication?
Yes, under Account → Security. With an authenticator app (Google Authenticator, Authy, Aegis). Recommended for anyone working with sensitive student data. Guide: Account & security.
What is the recovery key?
At registration you receive a 12-word phrase. It is the only way to restore the key if you forget your login password. We do not have it. Keep it safe (a password manager, or printed and stored in a safe). Details: Encryption.

Sharing with colleagues

How do I share a subject with colleagues?
Open the subject → “Share” → enter the colleague’s email address → “Add”. The person must already have a ClassCheck account. The related class list is shared automatically. Full guide: Sharing & collaboration.
What can an invited person do?
Invited people always have full edit access: view and enter grades, create columns, view notes, and export. Only the owner can delete the subject, invite more people, and change the weighting.
How does someone accept an invitation?
The invited person receives an email and, the next time they log in, sees the invitation on the dashboard in the “Invitations” section. Clicking “Accept” turns access on.
Can I share column presets with colleagues?
Yes. Under Settings → Column Presets, click the share icon next to a preset. Your team then uses the same assessment types.

School license

What is a school license?
A central license for several teachers at one school. One person pays, and colleagues unlock their accounts with a shared school code (for example CV-XXXX-XXXX, or older codes). It costs less per teacher, and the school administration gets a single invoice. More: School license.
How do I redeem the join code?
Log in → Pricing or Account → enter the school code → “Redeem”. The school license is active immediately. Step by step: Guide.
We have new colleagues. How do I add them?
If the license still has free seats, pass the join code on to colleagues. If no seats are free, the license admin frees an unused seat (for example from a teacher who has left the school) or adds seats to the license.

Assessment & calculation

How does weighted grade calculation work?
You set a percentage share for each category (for example classwork, tests, exams). ClassCheck converts each assessment to a percentage, averages each category, then combines them by weight. With a worked example: Grade calculation.
How can I mark excused lessons?
Press e in the cell. The field is marked “excused” and does not count toward the average — whatever the grading system.
Can I exclude individual columns from the average?
Yes. The pencil in the column header opens the menu. Turn on “Excluded from the average”. The column stays visible but drops out of the calculation. Useful for practice tests or one-off grades.
Where do I find keyboard shortcuts?
Press ? in any grade table. Full list: Keyboard shortcuts.

Data & export

Can I import students from a list?
Yes, by CSV import: open the class → “Import CSV” → paste a first-name and last-name list. Up to 500 students per import. Guide: CSV import.
Can I export my data?
Yes, in three formats: CSV (for Excel or Sheets), Excel (with color formatting), and PDF (for printing). Account settings also offer a full GDPR export of all data as JSON.
What happens to my data at the end of the school year?
Nothing automatic — your data stays. We recommend archiving last year’s classes (they leave the dashboard but remain available) and creating new classes for the new school year.
I deleted something by accident. Help!
Classes, subjects, columns, and students go to the recycle bin, where you can restore them or delete them permanently. Inside a table, Ctrl+Z undoes the last entry.

Technical issues

Which browsers are supported?
All modern browsers: Chrome, Firefox, Safari, and Edge (current versions). End-to-end encryption needs the WebCrypto APIs — no trouble from Chrome 67, Firefox 60, and Safari 14 on.
Does ClassCheck work offline?
Partly. The app loads offline, and saved data can be read. New entries need an internet connection (they sync through the server). If the service is fully down, the offline fallback page appears.
How do I report a bug or a request?
Write to us at hi@classcheck.net. For bugs, please say what you did, what you expected, and what happened. A screenshot is often worth a lot.
I need training for my staff.
Gladly. Write to us at hi@classcheck.net — we offer online introductions for schools that have a school license.
